Overcranking - what do I do in post???

[Eric Bader]

Hi, I'm new to this site, so this issue may have been addressed, but I have footage that I shot 60fps 2K (actually 59.97fps) on Red and I cannot figure out how to play it back at 24fps to actually see the effect. In camera, on Red Cine, and in Quicktime it always plays back at 60fps.

When you want to overcrank you should leave your project time-base set at 24fps, and set 60fps as the varispeed frame rate under the shutter menu. If you set the time-base to 59.97 (as it sounds as if you have done) you are setting it to play back at that rate.

It is obviously better to get this right when you shoot, but if you have overcranked footage you need to convert, then Cinema Tools can change the time-base of a QuickTime movie, but you will still have 59.97 timecode, which is not ideal.

Is there anything to do in post to convert that to slow motion and retain the extra frames?

Thanks!

It was shot incorrectly. The timebase inside the camera should stay at 23.98 (or 25fps, or 29.97) and you use VARISPEED to overcrank or undercrank. Then, when you play back the footage in camera or in any of the post tools, you'll get the expected result.

In this case, I think you can change the playback framerate in RedCine. In the Project tab, change the framerate from 59.94 to 23.98 (or whatever your base framerate should be). You might be able to export with the new framerate baked in.

Yes. See the second paragraph I added to my reply.

Whoops, Nick beat me to it. :)

If you want to change the frame rate in Redcine you need to not only set the project frame rate to 24, but change the time-base of the clip. You can do this by clicking on the lower part of the thumbnail in the library to bring up clip meta-data which can be edited. Not sure what this will do to the time-code though.

EDIT: just checked, and it changes the time-code rate to 24fps. This is a dangerous thing to do though, and should be treated as a one way manual process. I would not expect an offline/online workflow to work with these clips.

your best bet is to export your clip as a still sequence in redrushes/redcine/redalert and then import it in the the proper timeline in your editing software.

Thanks for the tips guys, I'm a film student testing the camera, and we have the tendency to screw things up.

The Cinema Tools timebase change seems to have done the trick on the quicktime files I created. Thanks again!

Screwing up is the best way to learn anything :-)
